OIL BURNER.

Application filed March 24,

My invention relates to the general art of burners, and belongs more particularly to that class known as oil or hydrocarbon burners, adapted for use wherever found applicable. The invention has among its objects the production of a burner and system of the kind described that is simple, compact, durable, reliable, efficient and satisfactory for use wherever found applicable.

Many other objects and advantages of the construction herein shown and described will be obvious to those skilled in the art from the disclosures herein given.

To this endmy invention consists in the novel construction, arrangement and combination of parts herein shown and described, and more particularly pointed out in the claims.

In the drawings, wherein like reference characters indicate like or corresponding parts:

Fig. l is a view in elevation illustrating my burner and apparatus adapted to be used in connection therewith;

Fig. 2 is a sectional View of the burner taken substantially on line 22 of Fig. 3;

Fig. 3 is a top plan view of the same, with the battle removed; and

Fig. 4 is a sectional view taken substantially on line 44 of Fig. 3. v

Referring to the drawings, in which the 'preferred embodiment of my invention is shown, 1 represents a chambered part preferably provided with the two chambers 2 and 3 separated by the partition or web 4 and a central part whichis provided with an opening through the same. The member 1 is recessed as indicated at 5 about the opening, and the pipe 6 positioned therein, so that a chamber 8 is formed, the top side being closed by the member 7. 6 is shown formed with openings 9 therethrough communicating with the chamber 8. The member 1 is preferably supported on an apertured plate 10 having a flange 11 about the same, the lugs 12 on one part maintaining the parts inspaced relation. As shown, the plate 10 is provided with an opening 16 at the middle extending substantially from side to side, being a flange about the same. This flange is preferably of such height that it seats against the bottom of member 1.

Extending to the burner is afeed pipe 17 or t The member he desired size, which extends to a source 1824. Serial 120. 261,432.

of oil supply. Arranged within the feed pipe 17 is a feed pipe 18, l9'being material such as asbestos or the like which forms a filler about the pipe 18 and centersthe same.

When oil is fed to the pipe 17, which is connected with the chamber 2, the same may flow freely through the pipe 18 tothe-chamher. A portion of the oil canseep through the melting 19 at the outside of pipe 18, capil. ary attraction as well as a slight head on the oil tending to cause a portion of the oil to travel into the chamber in this manner. The part 1 being hot by Virtue of the burning oil vapor, as hereinafter described, the oil is vaporized in chamber 2 and discha ed through the pipe 24, as will be herei alter described.

It may be mentioned that the pipe 24, preferably extends into the chamber 2, as indicated at 25.

Extended to chamber 3 is a water pipe 21, within which is arranged a pipe 22, 23 representing packing material or filling such as asbestos or the like. The flow of Water through the pipe 22 and packing 23 is similar to the passage of oil to the chamber 2. A discharge pipe 29, which preferably projects to the interior of the chamber 3, as indicated at 30, extends from the chamber to a point below the opening in theburner pre-. viously described. V r c r Referring particularly to Fig. 4, pipe 24 extends below the sleeve 6 as shown, and is constructed with a port 27 and opening 28, the end being closed by the plug 26. The pipe 29 projects below the pipe 24 and is provided with a discharge port 33 adjacent the opening 28 in the pipe 24, the end of the pipe being closed by a plug 31, and an opening opposite the port 33 is closed by the plug Generally, I prefer to arrange a baffle plate or spreader 34 above the burner opening, the same being supported or maintained in place in any suitable manner. As shown, the same is suspended from a chain or other connector 35' from a cross-bar 37 which may be supported by the standards 36. Obviously, any equivalent means for supporting the spreader plate 34 may be employed.

In Fig. l, I have illustrated more or less' diagrammatically the burner installed in a furnace or boiler 39. It may be mentioned that the boiler, furnace or heater may be of any preferred construction, the same in it-" Ill) trated, 40 represents the grates or any equivalent support, and 41 preferably an annular ring shaped base surrounding the burner but with a space therebetween andpreferably of fire brick, cement or the like. l1 have shown the fuel pipe 17 connected with the I fuel tank 42, and the water pipe 21 connected with a source of water su ply, for example, tank 54. In the particu ar installation illustrated, a pipe 43 extends from the tank 42 to an auxiliary tank 44 which is constructed so as to maintain a substantially constant head of oil, whereby the feeding to the burner is uniform. I have not shown details of construction of this auxiliary tank as the same may be modified more or less as desired. It may be mentioned, however, that as shown, a float45 controls the admission of oil'to the tank, 46 being an automatic drip valve which will cut off the supply in the event there is any leakage of oil. The pipe 49 connected with the tank 44 and pipe 17 may be provided with suitable valves, for example, as indicated at 48. I have shown diagrammatically a filter 47 arranged within tank 44, which will strain the oil fed to the burner. I have shown a drip pan 5O arranged below the burner and arranged to discharge into a shut-off valve cup 51 connected with the valve 52, so that in the event there is any leakage of oil from the burner, instead of flooding, the same will automatically shut off the supply, thereby preventing possible fire hazard as well as unpleasant flooding of the boiler room. Any

type of automatic shutoff may be used, that shown being merely for illustration.

The water feedpipe 53 from the water mains is connected with the tank 54, and it may be mentioned that I prefer to maintain in the tank an air cushion so that the level of the water is substantially belcw'the top'of the tank, the same being shown for purposes of illustration as at 57 I also prefer to extend the pipe 55 to adjacent the bottom of the tank and provide a filter or strainer 56. Such shut-off valves and other apparatus as desired may be employed."

The operation of the device may be briefly described as follows: Oil is fed to the burner through pipe 17 at substantially an even pressure or rate of flow, and water is fed to the burner through pipe 21 also at a substantially constant pressure or rate of flow, it being possible by means of the various valves to control. the rates of flow as desired. I have not endeavored to illustrate the several controlling valves in detail, but it may be mentioned that these may be so arranged that they will operate in unison and in a predetermined manner so that variation of the oil feed will cause a variation of the water feed. In start:

same to be discharged into the pipes 24 and 29. Steam will be discharged through the port 33 and opening 28 and with oil vapors through. 27 into the openingor bore of the sleeve 6, and when ignited will burn at the outer end of the tube 6 with an intense heat. The same will be deflected out under the spreader 34 and strike the inner walls of the boiler or furnace. The vaporized steam and oil will carry air from below the burner up with it, thereby affording perfect combustion. I have found that by providing the chamber 8 with the ports 9, that the flame will not run down into the tubular opening of the burner but will be always maintained at v the top where it should be. Of course, after the burner is in operation, the same becomes intensely hot so that the vaporizing in the chambers 2 and 3 becomes complete. However, the admission of the oil and water to the chamber and the constant vaporizing therein prevents the burner from becoming excessively hot. I have found that by providing the packing 19 and 23 about the feed pipes 18 and 22,-that the pipes are prevented from getting excessively hot as the oil or water passing up through the packing tends to maintain these pipes cooler than would otherwise be the case if the packing was omitted, The result is that boiling of the oil and carbonizing of the same in the pipe 18 is prevented and resulting trouble eliminated. Likewise, the water will not boil in pipe 22, and the deposit of lime, etc., is prevented- The result is that the burner will function and operate perfectly and efficiently for long periods of time without cleaning. It will be noted that there are no small ports or openings which may easily and quickly clog up or carbonize, thereby causing trouble as well as lowering the efliarrangement and combination of parts herein shown and described or uses mentioned.
